Answer:
<u>C) −12/5⋅(7/12⋅1/9)⋅8/5=(−12/5⋅7/12)⋅(1/9⋅8/5)</u>
Based on the data, the most likely correlation coefficient would be -1.
The slope between 20 and 30 days is -1, and it represents the change in the surface area of the lake per day.
The data represents correlation, not causation.
Since the data would form a perfectly straight line through the points, the correlation coefficient would be -1 for a perfect decreasing fit.
To find the slope, find the change in the surface area between those days, the change in the days, and write it as surface area/days: 80-90=-10; 30-20=10; -10/10=-1
This is not causation because there could be lurking variables we cannot see.
Answer: Each person will take
of the pie.
Step-by-step explanation:
Given : One pie is shared equally by 6 people.
The total number of persons = 6
Now, the fraction of the whole pie each person will take :-

Therefore, the fraction of the whole pie each person will take= 
Question:
You are ordering short-sleeve shirts (x) for $10 and long-sleeve shirts (y) for $15. Your budget is $300. Write the equation and find the intercepts.
Interpret their meaning.
Answer:
The x-intercept shows that you can buy 30 short-sleeve shirts and 0 long-sleeve shirts.
The y-intercept shows that you can buy 20 long-sleeve shirts and 0 short-sleeve shirts.
Step-by-step explanation:
Given
$10 per short sleeve
$15 per long sleeve
Budget = $300
The above can be represented as:
Total Cost of Short Sleeve + Total Cost of Long Sleeve = Budget
i.e.


To solve for the y intercept, we set x to 0


Divide through by 15

<em>This implies that, you can buy 0 short sleeves and 20 long sleeves</em>
To solve for the x intercept, we set y to 0


Divide through by 10

<em>This implies that, you can buy 0 long sleeves and 30 short sleeves</em>
